Topically applied anaesthetics may lead to a serious keratopathy. Three patients presented to us with disciform keratitis, peripheral corneal ring, and stromal infiltration following the topical use of oxybuprocaine. ⋯ In all three patients oxybuprocaine was dispensed over the counter by a pharmacist. Legislation for the restriction of over-the-counter sale of topical anaesthetics, steroids, and antibiotics is essential in the prevention of many of the self-induced ocular disorders seen in developing countries.

A 29-day-old infant born of consanguineous parents had type 1 hyperlipoproteinaemia associated with lipaemia retinalis. Biochemical analyses disclosed hypertriglyceridaemia, hyperchylomicronaemia, and lipoprotein lipase deficiency. ⋯ The plasma lipoprotein levels and fundus condition became normal after her ingestion of fat was limited. To our knowledge this is the youngest patient reported with type 1 hyperlipoproteinaemia associated with lipaemia retinalis.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparative efficacy of orally and topically administered beta blockers for chronic simple glaucoma.
This open study of beta blockers in chronic simple glaucoma compared the efficacy of once daily (o.d.) oral nadolol therapy with twice daily (b.d.) topical timolol therapy. Sixty eight patients were randomly assigned to starting doses of either 20, 40, or 80 mg of nadolol o.d. (51 patients) or 0.25% timolol b.d. (17 patients) and were seen at weekly intervals for a four-week (short-term) period. Upward dosage titration (80 mg o.d. maximum, nadolol and 0.5% b.d. maximum, timolol) was permitted if, at any visit, the intraocular pressure (IOP) in either eye was greater than 21 mmHg. ⋯ Long-term therapy (up to 24 months) in 28 nadolol patients and 5 timolol patients indicates no more likelihood of tolerance with nadolol therapy. Patient withdrawals from the study due to adverse reactions occurred with nadolol but not timolol. Since oral nadolol administered once daily is as efficacious as b.d. topical timolol, it can be recommended as first-line therapy for certain subsets of the glaucoma clinic population.

Sixteen cases of ocular injuries serious enough to require admission to Ibn-Sina Hospital, Kuwait, Arabian Gulf, due to explosion of glass bottles of carbonated soft drinks are reported over a period of 14 months from the beginning of July 1981 to the end of August 1982. Prevalence was much greater in the summer months and among children. ⋯ High environmental temperature and defective bottles were the most important predisposing factors. Preventive measures we suggest are better standards for manufacturers, more careful inspection of returnable bottles to detect defective ones, a separate detailed warning label on all bottles, and health education especially of school children about this and other risks of serious injury to the eyes and other parts of the body.
